T0 @ZZ whom it may concern:

Be it known that l, CHARLES F. SKELLEN- GER, a citizen of the United States, residing at Hubbard, inthe county of Hardin and State of Iowa, have invented a new and useful Buggy and Vagon Tire, of which the following is a specification.

This invention has relation to improvements in wheels, the objects in view being to increase the life of the Wheel and prevent the same from becoming dished or buckled by reason of the expansion and contraction of the spokes, fellies, and the tire during Wet and dry weather, and to provide means whereby even an inexperienced person may so adj ust the Wheel as to compensate for the contraction and expansion of the same as caused by the weather. l/Vith the above general objects in view the invention consists in certain features of construction hereinafter speciiied, and particularly pointed out in the claims.

Referringto the drawing, Figure 1 is a circumferential section of a portion of a wheel constructed in accordance with my invention. Fig. 2 is a plan View, the dogs removed. Fig. 3 is a perspective view, of the sliding dog. Fig. 4 is a similar view of the fixed dog. Fig. 5 is an inner view of those portions of the rim or tire occurring opposite the dogs.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents the rim, and 2 the spokes, of an p ordinary wheel, one of the fellies of which has been replaced by a malleable cast-metal felly 3, which felly is of U shape in cross-section and provided near its opposite ends with blocks 4, having openings 5 for the reception of the spoke-tenons in the usual manner. Upon one of the blocks 4 there is mounted a fiXed dog G, in front of which there is formed upon the inner sides of the felly opposite ribs '7 which ribs fit in and form guiding-Ways for opposite grooves 8, formed in the sides of the dog, which at its rear end is provided with a shoulder 9, abutting against the end of the block 4, and above the shoulder is provided with a tail-piece or extension 10, which overlaps said block. The blocks 4 are of such a height as not to be flush with the edges of the felly, and the dog 6 fills the space remaining, so

that its upper surface is Hush with the edges of the felly, with the exception of a series of transversely-inclined teeth 1l arranged across the outer iace of the block, said teeth extending slightly above the edges of the felly. The opposite block 4 receives the movable or ad` justing dog12, which,like its companion dog, is provided with a series of transverse teeth 13, extending slightly above the edges of the felly and disposed in a direction opposite to the disposition of the teeth 11 of said opposite dog; or, in other words, theteeth are disposed toward each other. The dog 12 is provided upon its under side with a shoulder 14, and extending over the same is a tail-piece or eX- tension 15, which overlaps the block 4. Between the shoulder 14 and the teeth 13 the dog is provided with a flared socket 16, in which is fitted a similarly-shaped head 17, formed upon the outerend of an inclined drawrod 18, the opposite end of which projects through an inclined bore 19, formed in aswell 2O upon the inner edge of the telly-section. Beyond the end of the bore the rod is threaded, as at 21, and mounted upon the same is abinding-screw 22, so that, as will be apparent, the dog 12 may be operated within the telly so as to move in either direction.

23 represents the tire, which is secured to the fellies in the usual manner and to the dogs G and 12 by means of screws 24, inserted at suitable intervals in countersunk openings 25, formed in the tire, the ends of the screws taking into the dogs. The tire at those portions occuring opposite the teeth 1l and 18 is provided with a series of transverse teeth or notches 26, into which take the teeth 11 and 13, the teeth of the tire being oppositely disposed to each other and to the teeth of the dog engaging the same, so that any movement upon the part of the sliding dog will cause a similar movement upon the part of the tire, and the dog 6 being stationary will act as a holding-dog for 011e portion of the tire, while the opposite portion is either expanded or contracted.

It is well known that dampness will cause a swelling of the parts of y the wheel and if the rim be unyielding the spokes will become crooked or sprung and the wheel dished. Again, if the wheel be set for wet weather IOO and a dry spell occurs, the parts of the wheel will shrink away from each other, thus causing a looseness and consequent rattling. By my invention, however, when wet weather occurs a few turns of the binding-nut 22 in a retrograde direction permits the sliding block to loosen and the parts to readily expand, and when dry weather occurs the laxity oi' the parts maybe readily taken up by binding the nut snugly down upon the rod.

In wheels where the metal telly described is employed I may, if desirable, provide said wheels at a diamet-rically-opposite point with a plane connterbalancing metal telly, as will be readily understood. c

Having thus described my invention, what I claim is- 1. In a wheel, a hollow section provided near one end with a toothed holdingdog and near the opposite end with a toothed movable dog, in combination with a tire having teeth or notches engaging` by the respective dogs, and means for operating` the movable dog, substantially as specilied.

2. In a wheel, a metal telly-section made hollow, a fixed toot-hed dog arranged in the same near one end and an oppositely-toothed movable dog arranged in the same near the opposite end, an inclined swell having a bore registering with a flared opening formed in the movable dog, a binding-bolt terminating in a head itting in the socket and extending from the bore, a binding-nut mounted on the rod, and a tire mounted on the telly and having notches or teeth occurring opposite those of the dogs and arranged in opposite directions thereto, so as to interlock with the same, substantially as specified.

3. In a wheel, a felly formed of metal and U-shaped in cross-section, provided with a pair of blocks within the same having spoketenon -receiving openings and terminating short of the edges of the felly and between t-he blocks provided with a swell having an inclined bore, a fixed dog having a shoulder abutting against one of said blocks, and an extension overlapping the same, and with a series of transversely-disposed teeth, a movable dog provided with a similar shoulder and extension abutting against and overlapping the opposite dog and provided with a series of Y transverse teeth arranged opposite to those of the opposite dog and provided with an inclined flared socket registering with the bore of the swell, a headed rod mounted in the socket and projecting through and beyond the bore, a binding-nut mounted on the end of the rod, and a tire mounted over the t'elly and secured thereto by bolts, the heads of which areY
